Specification of Letters Patent.

Patented June 30, 1908.

riginal application filed June 2, 1905, Serial No. 263,398. Divided andthis application filed July '7, 1906. Serial To all whom it may concern:

Be it known that I, ROBERT KIESERLING, a subject of the King of Prussia,and a resident of Altona, (Elbe,) Germany, have in vented an Improvementin Cement Paving, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in cement aving, this applicationbeing a division of t e application ed by me on the 2nd day of June,.1905, Serial N 0. 263398, for improvements in cement paving, and forwhich a patentwas granted to me Dec. 25, 1906, No. 839,600.

According to my present invention I embed in a layer of concrete orcement, which may be upon a second such layer, gutters of U or Vsection; and I fill these gutters with some elastic substance, such astar, masticcement, or the like. From the walls of the gutter projectlugs, which are surrounded by the concrete, whereby the gutters arefirmly held in place in the material.

The purpose 'of my invention is to simplify and cheapen the constructionshown in the patent above referred to. 7

My invention is illustrated in the accompanying drawings, in whichFigure 1 is a plan, showing a portion of a street paved according tothis invention. Fig. 2 1s a cross section of a portion of theconstruction shown in Fig. 1 drawn to a larger scale. Fig. 3 is a sideelevation of a gutter section as shown in Fig. 2. e

The pavement consists of two superposed concrete layers a b. In theupper layer a there is embedded a metal gutter c, which may either restwith'its base upon the surface of the lower concrete layer 6, or mayterminate at some distance above this layer 72, so as to leave a layerof concrete between it and the latter, as shown in Fig. 2. d are lugs,stamped out of the walls of the gutter c and bent over outwardly. Theselugs are naturally firml embedded in the concrete a and thus aflor thegutter c a thorough hold. After the pavement has been laid and theconcrete has set, the tter c is filled with an elastic material e, sucas tar, mastic-cement,

caoutchouc, so that water can not collect in crete.

it. If desired, the gutter may be filled in this manner rior to beingembedded in the conthe drawings a gutter of U-section is shown, but asalready remarked, a V or any other suitable section may be adopted.

The gutter as a rule will naturally not be in one continuous piece, butwill consist of a number of se arate lengths; and these are preferablylaid directly adjacent or in close proximity to the curb j} and the twoouter gutters 9 thus formed are connected at intervals by cross guttersh.

The gutters k can consist of two lengths which meet together at themiddle of the street in an obtuse angle, so that when heavy carts passover the same the stress will be met by two walls of the gutters andalso by a part of the aving.

Having thus descri ed my invention, what I claim as new and desire tosecure by Letters Patent is 1. Cement paving for streets comprising incombination two layers of concrete, two nar row gutters provided in theupper layer near to the longitudinal edges, a number of gutters dis osedtransverse to said first gutters, and a filling of plastic material inall of said gutters, the gutters being ofa substantially U-shapedcross-section and provided with means for anchoring the same,substantially as and for the purpose set forth.

2. Cement paving for streets comprising in combination two layers ofconcrete, two narrow gutters provided in the top layer near to thelongitudinal edges, transverse gutters meeting together in an obtuseangle, and a filling of lastic material in all of said gutters, whicgutters consist of resilient metal bent to a substantially U-shapedcross-section and provided with anchoring lugs, substantially as and forthe purpose set forth.

3. Cement paving for streets comprising in combination two layers ofconcrete, gutters of resilient metal bent to a substantially U- shapedcross-section provided in the upper layer and having a number ofintegral lugs 1n the side walls thereof, and a filling of plasticmaterial provided in each of said gutters, substantially as and for thepurpose set forth.
